Applicationiled 'May 19, 1969. Serial No. @6.967.

To whom it may concern:

known that l, lVrLLrAM ELLIOTT, of lfitisburg, in the county of Allegheny and State el nnsylvania, have invented a new and useful lmprovemerrtJ in Motors, of which the following is a full, clear, and exact description, 'reference being had to the accompanying` drawings, forming part of this specification, in-which Figure 1 isa longitudinal section of' one form of motor embodying my invention; Fig. 2 is a View partly in front elevation and partly in transverse section; Fig. 3 is a View similar to Fig. 1 showing a modification, and Fig". 4t 'is a section on the. line lV-IV of Fig. 3.

My inventionY has relation to rotary motors, and is designed toprovide a motor which shall be simple and compact in its construction; and in which the parts are so constructed and assembled as to render them readily accessible as to renewal or repairs.

The nature ofV my invention will be best understood by reference to the accompanying drawings in -which l have shown the v preferred embodiments thereof, and which In the drawings the numeral 2 designates an outer casing or shell` formed at its front and rear ends with the heads and l respectively. When the motor is to be used for the purpose of operating boiler tube `cleaning tools, the motor being carriedthrough the boiler tubes with the cleaning tools, the casing or shell together with the heads, are of cylindrical form, as shown; but for other purposes the shape of the casing or shell and heads may be modified as may be desired. y

5 designates the shaft ofthe motor which is journaled in bushings 6 and 7 the bushing 6 has a flange 8 at its inner end seating forwardly against a shoulder 9 in the head 3.

10 designates the piston blade, which is seated in the slot of the shaft 5 in the usual manner and which rotates within the cha1nber of' Ya cylinder 11 seated within the casing or shell 2. rlhis cylinder has a piston chamber formed eccentrically therein, the ends of the cylinder being closed .bythejcilk cular plates or disks 12 and 13. The disk 12 seats between the front end of the cylinder and the flange 8 of the bushing 6, While the disk or plate 11 seats between the rear Aend of the cylinder and the iiange 14 at the inner end of the rear bushing 7. The bushing 7 is a split bushing and is seated in a cap member 15' which is provided with a space or chamber 16 at the rear of the bushing 7 to receive a head Aor collar 17 on the rear end of the. shaft 5. This collar has a thrust bearingagainst the rear end of the bushing 7 to prevent any endwise movement'V to the shaft 5 in a forwarddirection; and the shaft has ansh'oulder 18 fitting against the inner end oi the bushing 7 to take up end thrusts inthe opposite direction. A space or chamber 19 is left behind the head roiecollar 17; and from this space a vent passage 20 extends `obliquely through the cap 15 and connects at its outer end with a` -discharge opening 21 in the shellcasing 2.

rEhe head l has an internal thread 22 for engagement with the exterior thread of a. socket member 23 screwed into said head and having a threaded-opening 24 for connection with a suitable supply pipe (not shown). The interior of the socket member and the rear end portion of the cap 15 are shaped to form an admission space or chamber 25 from which an admission port 26 leads forwardlythrough the capmember 15;

the flange Iof the bushing`7,^the plate orl disk 13 and thence extends longitudinally 'through thethiekened wall of the cylinder 11,'whieh portcommnnicates with the piston chamber by a plurality of cross, ports 27.

28 is an 'exhaust port which is also formed. in the. thick portion of the wall of the cylinder and which extends forwardly through the plate'or disk 12, the liange of the bushing 6 and the front head 3 being arranged to discharge at the front side ofV said head,

This exhaust port communicates with a piston cylinder by a plurality of cross ports 29. The cylinder 11 may be conveniently held against rot-ation with the casing or shell by means of a pin or rivet rlheinner head end 31 engages the longitudinal slot or recess'32 cut in the outer surface of the cyl removed for renewal or repairs;

inder;` The end vplates or .disks 12 and lb,

haust passes ".nto the poit 28 through the crossports 29 and is discharged at the front end of the motor. The provision of the space or chamber 1'9 and vent port 2( is .for the vpurposeofvpreventing the accumulation of any back pressure at the rear end ofthe pis# the rear shaftbearing. y' y The front endfoftheshaft 5 may be pro- Jvided' with a threadedl shankf34 or other suitable means'for theattachment thereto ofthe curingl member engaging theremovable head g5 andholding it in place, and a piston shaft journaled in said heads and carrying a pis- -'toni blade between-the'two wear plates, said 2E power tube cleaning tool or otheilpdev'ice' which isto be operated bythe moton Y The partscan'be readily'iassembled withinl the casing or'shell'; being readily'and quickly secured inthe proper relation by the-means described. 'When'the socket-23 is screwed into its seatinto head 4,. its'inner end bears against the cap'l' and thereby effectively secures the parts' against endwisefmoveinent against the casing or shell. By unserewing the socket member, the parts maybe readily Inl? 3 and 4 I have-illustrated ventipn as applied to atandem'fino'tor having the two cylinders and 36 pla'oed'end' to 3.5 end, their inner ends being separated bythe plate'orfdisk 37 which forms the inner headofboth'icylinders'.
